Some of the concerns with DIY toilet installation include allowing dangerous sewer gases to escape during the process and not positioning the toilet properly to avoid leaking after the fact. In most homes, toilets get a lot of use and they need to be installed correctly in order to avoid any negative effects. If your toilet is broken or damaged, it’s also wise to call for professional help instead of trying to fix it yourself. Get it done right and then you can rest easy, knowing it won’t leak or stop working when you need it.
